WIRE-FENCE TOOL.

SPECIFICATION forming part of Letters Patent No.. 718,243, dated January 13, 1903.

Application led January 11, 1902. Serial No. 89,310. (No model.)

To au whom it may concern:

Be it known that I, FRANK CANFIELD, acitizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Wire Fence Tools; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification. Y

My invention relates to improvements in tools for applying clips or fastening devices to the wiresand stays at their intersections in wire-fence constructions, my object being to provide a device of this class which shall be simple in construction, the elements being so combined and arranged as to exert great power and possessing the requisite durability and efficiency for a tool of this class; and to these ends the invention consists of the features, arrangements, and combinations hereinafter described and claimed', all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a top or plan View of my improved tool. Fig. 2 is a section taken on the line w x, Fig. 1. Fig. 3 is a front end elevation of the tool with the detachable die-plate removed. Fig. 4 is a section taken on the line 'y y, Fig. 1. Fig. 5 is a section taken on the line .e z, Fig. 2. Fig. 6 is a perspective view in detail of a split keeper applied to each die member. Fig. 7 illustrates a wire and stay fastened by the clip members, showing the result of the operation of my improved tool. Fig. 8 is a face view of the detachable abutment-plate.

The same reference characters indicate the same parts in all the views.

Let the numeral 5A designate the body or frame of the device, in which is incased a reciprocating plunger 6, provided at its forward extremity with a die 6, which is fast therein and provided with a counterpart cavity 6c, adapted to receive the central part of one of the members 7 of the fastening-clip. The

face of the die around the central cavity is also provided with four recesses 6d, adapted to receive the projections of the clip members forming the seats for the wire and stay. The die has a central opening in which is placed a keeper 8, slotted or bifurcated to straddle a central plate 9, fast in the die. The forward extremity of the keeper passes through an opening in the central part of the 6o l clip member and holds the said member temporarily in place preparatory to applying the clip to the wire and stay. The rear extremity of this keeper is acted on by one extremity of a coil-spring 10, whose opposite extremity engages a stop-pin 12, fast in the plunger. This spring normally'holds the keeper in the protruding position-that is to say, with its forward extremity projecting forwardly from the bottom of the cavity c-in order that it 7o may enter the opening in the clip member and support the latter in place. As pressure is applied and the wire is forced rearwardly into the cavity of the clip member the keeper is forced rearwardly against this spring, compressing the latter. The body or framework 5 of the device is composed of two side channelbars 5a, connected by top and bottom plates 5 and 5d, respectively. The forward extremities of the side bars 5@ are horizontally slotted in 8o the plane of two of the recesses 6d, as shown at 5g, to receive the wire 13. The bar extremities are also provided with vertical grooves A, intersecting the slots 5g at right angles,

adapted to receive a plate 14, forming an abutment cooperating with the plunger in applying the twin clip members to the wire and stay. The vertical sides of this plate 14 engage the grooves of the bars 5a, thus making this plate 14 a fixed or rigidly-detachable die- 9o plate. This plate is also provided with shoulders 14a, which support it in position, preventing it from slipping downwardly through the bars.

The plate 14 is provided with a central diet 95 The die 14 Ioo straddles a plate 16, fast in the die. The parts of the keeper on opposite sides of the plate normally spring outwardly, whereby the keeper is self-retained in the die member. It, however, yields to forward pressure in order to allow the stay 17 to move forwardly into the central cavity of the clip member.

The means for and the manner of operating the plunger will now be described. Pivotally connected with the pin 12 on opposite sides of the plunger, which is recessed or eut away for the purpose, are two links 18, whose opposite extremities are connected, by means of a pin 19, with the bifurcated extremity of a hand-lever 20, fulcrumed at 2l between the rear extremities of the bars 5^. The lever 2O and the links form a toggle-joint for operating the plunger. Another hand -lever 22 passes between the arms 20 of the bifurcated portion of the lever 2O and is pivotally connected with the pin 19, its forward extremity passing between two links 28 and under a roller 24, mounted on a pin 25, connecting the upper extremities of the links, Whose lower extremities, which protrude through openings formed in the bottom plate 5d, are connected by a pin 26, passed through openings in the link extremities outside of the said bottom plate.

Preparatory to using the tool the die-plate 14 is removed from the bars 5a and a clip member 7 placed against the die 6, the forward extremity of the keeper passing through an opening in the center of the clip member and supporting it in place, the levers 2O and 22 being separated to withdraw the plunger or move it rearwardly sufliciently for the purpose. The tool is then moved to a position causing the Wire 13 to enter the slots 5g of the channel-bars and engage the clip member as it is held in the die. The stay 17 is placed in position forward of the wire. Another clip member 7 is then placed against the die 14c of the plate 14, the keeper 15 being pushed rearwardly to enter the central opening of the said clip member. The die-plate 14 is then dropped to position between the channel-bars, (see Figs. 1 and 2,) after which the two clip members 7 are in alinement with each other on opposite sides of the wire and stay. The hand-levers 2O and 22 are then moved toward cach other from the dotted-line position shown in Fig. 2 to the full-line position in the same figure. 24 from beneath, which roller forms its fulcrum, the toggle members composed of the links 18 and the bifurcated forward part of the lever 20 are made to approach a straightline position, (see Fig. 2,) whereby the plunger is forced forwardly by the toggle action, and consequently with great power, toward the abutment die-plate 14, whereby the wire and stay are bent outwardly in opposite directions into the cavities or central openings of the clip members, the said members being at the same time forced together and the arm 7a of each member made to clasp or embrace the As the lever 22 bears upon the roller y other member, whereby the two members are held securely in place and the wire and stay fastened firmly together.

Having thus described my invention, what I claim is- 1. In a wire-fence tool, the combination with a frame, of a plunger slidable therein and provided with a die whose face is provided with a central cavity and lateral recesses leading outwardly from said cavity, an abutment-plate detachably connected with the frame in front of the plunger and provided with a central cavity and lateral recesses similar to those formed in the plunger, the dies of the two parts lbeing in alinement and arranged to coperate,and suitable means for actuating the plunger.
